Is it possible to do soft assertion in the karate

Question

Is it possible to continue the execution of test step even if one of the assert/match fails?

Ex:

Scenario: Testing
* def detail = {"a":{"data":[{"message":["push","dash"]},{"message":["data","Test"]}]}}
* match detail contains {"a":{"data":[{"message":["push","dash"]}]}}
* print detail

Here match will fail but execution stop at that point. is there a way to do a soft assertion so that next step gets executed?

Answer 1

EDIT in 2021 - a PR introducing a continueOnStepFailure flag was contributed by Joel Pramos here and is available in Karate 1.0 onwards. You can find more details here: https://stackoverflow.com/a/66733353/143475

If you use a Scenario Outline each "row" is executed even if one fails.

Scenario Outline: Testing
* def detail = { a: 1, b: 2, c: 3 }
* match detail contains <expected>

  Examples:
    | expected |
    | { a: 1 } |
    | { b: 2 } |
    | { c: 3 } | 

Note that the concept of "soft assertions" is controversial and some consider it a bad practice:
